 === Flasher for initfs with onscreen bootmenu ===

For safe flashing please do the following:

- close all aplications (to free available RAM and prevent system crash)
- disconnect from network (to prevent system crash)
- make sure you have at least 5MB free disk space in flasher directory
- make sure you know how to reflash device in usual way if this fails

Are you sure to continue? (yes/no) : yes
